Be itlmowntiiut I, LEWIS G. MoCmn'rocn, e citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Transformer Tanks, of which the following is a specification.

This invention relates to tanks and p21 ticularly to corrugated tanks, for instance for oil cooled transformers in which the tank body relatively large cooling surface for the oil. In such tanks, when made of sheet metal 113 and when the corrugations exceed a. certain depth, there is a. tendency for the n'essure of the contained oil to cause a bugging or warping oi the corrugations destioy ng t sir symmetry and sometimes interferrmg with The chief object of this invention is to rovide a tank in which the corrugations will be reinforced in simple and inexpen 'sive manner permanently sustaining the corrugations in their original shape without impeding the cooling effect and w th. out; detracting from the regular symmetrical ngpearnnce or the tank.

In the. accompanying drawings illustratin the invention,

*ig. l is a horizontal sectional view on line 1-4 of Fig. 2 of a large transformer tank illustrating one embodiment oi the invention. and

'Fig. .l is a. vertical sectional view of the same on line 52-42 of Fig. 1.

In the embodiment of the invention illus. tinted in the drawings a tank having a to) flan o T and bottom M has its body -0 deep y corrugated. The corrugations C have their outer bends at 5 and their inner bends at (l and between these the sides 7 o the corrugations eiztend as 'substcntiall plane sur faces zigzag iug at angles to one 1 5 other. The tops 8 an bottoms 9 of the corrugations are closed over in arch form am the corrugations overhang the top and bot tom of the inn]: and there are continuous air spaces extending between the corrugatop to bottom. Retaining hoops or bands 10 surround ihe body of the rank tightly encircling the outer hands of 5 of the corrugations and preiixrahly welded thereto to rigidly spnce these bends Between adjacent sides 7 of the corrugm epeeiflcaiion of Letters Patent.

They are is en:- seives of been conducting material and hazing hollow rovide a vertical ventilatmg passage t rough their interior. At the some time they have extended contnct with the sides of the corrugations and rigidly support these sides egainst bulging or warping in service. x

The pipe spneers are easily formed by simply cutting oil standard stock in proper length and they ma be applied to any tank by inserting them endwise 1n the outer position of the space hetween corrugations and then pressing them inward when properly positioned, finally bolting them in their inner most position. Where the spaces between the corrugations is narrower as at 17 (Fig. 1]) a smaller pipe may be substituted or the size pipe may be used slightly iattened. as shown. The invention is eaeilv adzvhteble to various tanks and its application is sinrple and inexpensive, the spacers intervening in even symmetrical manner between the corrugations.
